The nurse has taken shift report on her patients and has been told that one patient has an ocular condition that has primarily affected the rods in his eyes. Considering this information, what should the nurse do while caring for the patient?
A) Ensure adequate lighting in the patient's room.
B) Provide a dimly lit room to aid vision by limiting contrast.
C) Carefully point out color differences for the patient.
D) Carefully point out fine details for the patient.
Ans: A
Feedback:
The nurse should provide adequate lighting in the patient's room, as the rods are mainly responsible for night vision or vision in low light. If the patient's rods are impaired, the patient will have difficulty seeing in dim light. The cones in the eyes provide best vision for bright light, color vision, and fine detail.
